The basic network configuration options can be seen at the end of the Config Sample.

If your configuration file does not contain the network section, it probably means the version of Smoothie that shipped with your board is too old. You need to use the latest edge firmware, and use the latest configuration file. See Flashing Smoothie Firmware and Configuring Smoothie.

All options

Option

Example value

Explanation

network.enable

false

If set to true, enable the Ethernet network services

network.webserver.enable

true

If set to true, enable the web server service, on port 80, which provides a control and upload web interface

network.telnet.enable

true

If set to true, enable the telnet service, on port 23, which behaves much like a Serial interface

network.plan9.enable

false

If set to true, enable the plan9 network filesystem on port 564 which allows mounting the Smoothieboard

network.ip_address

auto

If set to auto, use DHCP to request an IP address. If set to an IP address, use that address as a static IP.

network.ip_mask

255.255.255.0

If using a static IP, define the mask for the network.

network.ip_gateway

192.168.3.1

If using a static IP, define the gateway for the network.

network.mac_override

AB.AB.AB.AB.AB.AB

If set, override the MAC adress for the Ethernet interface. Only set this if you have a conflict on your network.

network.hostname

shapeoko17

Some DHCP servers accept a hostname for the machine, which then allows you to connect to it using that name instead of it's IP.

Wiring

To access your Smoothieboard, you need to connect it to your network.

To do so, you plug an Ethernet cable into the Smoothieboard at one end, and into your Ethernet router at the other end.

Please note that you can't connect a Smoothieboard directly to your computer ( not unless you use a special type of cable and a special type of configuration on your computer ). You want to use a router for this.

Once configured and plugged in, reset the Smoothieboard and wait for it to connect to the network.

Accessing Smoothie

To access Smoothie over the network, you first need to know its IP address.

If you are not sure what IP address Smoothie has been assigned you can use one of the following methods :

If you have a panel connected to the Smoothieboard, the panel should display the IP address.

If you have access to your networks main routers administration interface, it should tell you the IP address of all peripherals connected to it.

If you are connected to the board via USB, you should be able to use a program like Pronterface to send the @net command, which gives you the current IP address.

If you are running linux, you can use a command like nmap -sn 192.168.0.0/24 to find all accessible peripherals on the network.

NOTE if the IP address shows 173.222.239.190 then it means that DHCP did not get an IP address assigned. (Try a static IP instead).

You can access Smoothie by using its network services:

Telnet (port 23) to run commands, stream gcode to Smoothie or connect from Pronterface (see below)

Telnet (port 23)

You can use a terminal to connect to your board via telnet, simply type in a terminal :

telnet ip_of_smoothie:23

Pronterface can also connect to Smoothie over the network by using telnet - just enter ip_of_smoothie:23 instead of the serial port before clicking 'Connect'. Where ip_of_smoothie is the IP address of your Smoothie. You must check the box under Settings Menu that says TCP streaming mode.

Better web interface

Multiple network access

DO NOT use the web interface and telnet at the same time.. this will crash smoothie.

Accessing while printing

For Smoothieboards v1, make sure you never access or refresh the web interface while the machine is executing a Gcode file. This can result in a crash. Just make sure you don't do it, load the page while it's not running, then use the page but do not refresh or re-load it. This is a limitation of the current firmware, we expect it to be possible to fix in v2.

Cache

If you have several interfaces, or installed a new one, whenever changing from an interface to another, make sure you fully clear your cache. See the documentation for your browser, or google about it, to find exact instructions for your setup.

Web interface

It allows you to control the machine over the network

Simple File Transfer Protocol (port 115)

Plan9 network filesystem (port 564)

NOTE plan9 is not built into smoothie by default, to include it rebuild smoothie with make PLAN9=1. See Compiling Smoothie.
The plan9 network file system can be used on Linux to directly mount the Smoothieboard over the network. At first activate the option “network.plan9.enable” and restart your Smoothie. After that you can mount with:

mount -t 9p 192.168.2.120 -o dfltuid=1000,dfltgid=1000 /mnt/smoothie

Now you can access the SD card of the Smoothieboard like a normal filesystem!

The dfltuid/dfltgid are the uid/gid of the user which owns the files in the mount. It is recommended to set these to the uid/gid of the user which will write to the filesystem.

If you want you can also add the filesystem to your /etc/fstab as follows:

Using a hosts file

If IP addresses are getting you down, you can address your smoothie by name if you add a line to your computer's hosts file. For example, assuming your Smoothie's address is 192.168.2.120, you could add:

192.168.2.120 smoothie

And then simply use smoothie:23 in the Port field of Pronterface, and simply http://smoothie in your web-browser.

This only works from the computer you edit the hosts file on, and requires smoothie to have a constant IP address, either through configuring smoothie as static IP, or by configuring your DHCP server to always assign Smoothie the same IP address.

Hardware requirements

To use the network capabilities of the smoothieboard (4X and 5X, note the 3X board does not have ethernet capabilities ) a RJ45 Magnetic Modular Jacks aka RJ45 network transformer like the Hanrun HR911105A needs to be soldered onto the board.

Net command

If your network interface doesn't work as it should, you can get some debugging information ( such as the current IP ) by sending the net command ( @net from pronterface ) command via the console ( USB or UART ).
